High performance current transducer measures up to 400 Arms

LEM has introduced the LA 306-S, a panel-mounted current transducer for the measurement of currents up to 400 ARMS (@ +70°C) or 300 ARMS (@ +85°C). The unit offers the high performance of a closed-loop current transducer at a very competitive price.

The new transducer is only 56mm high. It features a wide maximum bandwidth of DC to 50kHz and an overall accuracy of better than 0.7 per cent at the primary nominal RMS current. Typical linearity error is ±0.1 per cent at nominal current and the maximum offset temperature drift is 500 microamps from -40 to +85˚C. The closed-loop Hall-effect technology results in no insertion losses and a fast response time of less than 1 microsecond.

The transducer’s aperture accepts busbars up to 13 x 30mm. Specified with 2000 turns as standard, it is also available with 5000, 4000 or 3000 turns on request. A Molex 5045 plug is offered as standard for the secondary connections, to allow quick installation. A Molex series 70543 connector can be specified for a more robust connection.

With an isolation test voltage of 6kVRMS/50Hz/1min, the transducer complies with the EN50178 industrial standard. All materials used satisfy UL94-V0. The LA 306-S is CE marked and is supplied with a five-year warranty, as are all LEM industrial products.

Come and see us at PCIM  Hall 12.402 where you can find out more about these and other LEM products. We will also be presenting a conference paper on Thursday 24 May at 1400 hrs - A transducer at the limits of current measurement accuracy.
